What I think is great about Pippin, specifically, and I wouldn't make this generalization about all musicals, is that it is about how we tell stories and the way stories are very subjective. How we tell some things and leave other things out in the way The Princess Bride is or The Wizard of Oz is, which both have a framing device.
The moment you accept God's ordering, that moment your work ceases to be a task, and becomes your calling; you pass from bondage to freedom, from the shadow-land of life into life itself.
